Ensuring Safe Tank Operations During High-Flow Pumping

Introduction

High-flow pumping in industries that have large storage tanks, ship loading as an example, has unique safety concerns, for example ship loading. Safely operating tanks is important, but even more so when the material contained within the tank is a flammable liquid. This article will review the critical safety protocols and equipment that can assist in reducing the risks associated with these types of operations.

The Importance of Safety in High-Flow Pumping

Safety is important when filling and emptying storage tanks in order to prevent accidents and to also protect the tank from being damaged. The high flow associated with pumping can cause pressure and air volume changes to occur rapidly. Due to this, dependable safety features are required.

Risks Associated with Inadequate Ventilation

Many hazards are associated with inadequate ventilation, such as the over pressurisation or creation of a vacuum in a tank that can cause structural failure and catastrophic release. Incidents and accident records also show that most accidents are caused by poor ventilation systems.

Regulatory Standards for Flammable Liquids

For storage tanks with flammable liquids below a flashpoint of 60 °C, there are high safety restrictions. Within the German Technical Rules for Hazardous Substances TRGS 509, it is demanded that storage tank venting be equipped with flame arresters, which prevent flames from reaching inside the tank. An elementary necessity to reduce the risk of explosions.

KITO’s Advanced Solutions for Safe Tank Operations

KITO offers an innovative solution with bigger valves equipped with deflagration-proof flame arresters designed for continuous burning for explosion groups IIA to IIB3. These valves (up to DN 200) enable effective operation of high gas flow rates in various applications, like, for example, tank breathing. Valves offered by KITO can also be equipped with electrical heating as well.

Best Practices for High-Flow Pumping Safety

When operating in the high-flow pumping mode, these are best practices to follow for safe operation.

• Regularly inspect and maintain ventilation systems.
• Train personnel on safe tank operation protocols.
• Utilise appropriate protective equipment.
• Develop and implement emergency response plans specific to risks associated with high-flow operations.

Conclusion

In conclusion, it is necessary to ensure safe tank operations under high flow pumping conditions to prevent accidents and protect the integrity of both the facility and personnel. The application of good safety practices and state-of-the-art equipment such as KITO’s valves allows industries to minimise risks related to hazardous liquids.

A review of tank incidents over the past years shows that the majority were caused by poor ventilation during high flow pumping. Leading industry authorities agree that compliance with regulations and following best practices will guarantee safety.
